We have applied the infrared surface brightness (ISB) technique to derive distances to thirteen Cepheid variables in the LMC which span a period range from 3 to 42 days. From the absolute magnitudes of the variables calculated from these distances, we find that the LMC Cepheids define tight period-luminosity relations in the V, I, W, J and K bands which agree exceedingly well with the correspon...

A combination of analytic models and n-body simulations implies that the structural evolution of the Large Magellanic Cloud (LMC) is dominated by its dynamical interaction with the Milky Way. Although expected at some level, the scope of the involvement has significant observational consequences. First, LMC disk orbits are torqued out of the disk plane, thickening the disk and populating a sphe...

BACKGROUND We describe trends in participation by investigators from low- and middle-income countries (LMCs) in publications describing oncology randomized control trials (RCTs) over a decade. METHODS We used Medline to identify RCTs published in English from 1998 to 2008 evaluating treatment in lung, breast, colorectal, stomach and liver cancers. Data on author affiliations, authorship roles...

Context. RR Lyrae stars (RRLS) belong to population II and are generally used as a tracer of the host galaxy halo. Aims. The surface as well as vertical distribution of RRLS in the inner Large Magellanic Cloud (LMC) are studied to understand whether these stars are actually formed in the halo. Methods. RRLS identified by the OGLE III survey are used to estimate their number density distribution...

For high-speed packet transfer in the wireless environment, the shared radio medium is provided to mobile terminals (MT) through the control of MAC layer. Contention and polling technique are known as two fundamental methods that are used in this environment. This paper aims to compare the operation of these two methods if they are enhanced to use in a connected micro-cells system to support fo...

Logic reasoning presents notable difficulties for young children. This paper presents Logic Model Creator (LMC), a new environment that supports building and exploration of intuitive visual representation of logic models by young children. LMC logic models are structured as hypothesis, decision and / or counter decision components. These models are built using visual entities which represent th...

Recent investigations aimed at estimating the distance to the young LMC cluster NGC 1866 have made use of Red Clump stars in the surrounding LMC field, together with empirical and theoretical Main-Sequence fitting methods, and have found significantly different distances for the field and the cluster, the latter being closer by in distance modulus by ∆(DM)∼0.20 mag. In this paper we (re-)consid...

Isoantiserum (IS) inhibition of lymphocyte-mediated cytotoxicity (LMC) was studied using an in vitro (51)Cr release assay system. In the early phase of incubation, LMC was competitively inhibited by IS. However, as the incubation continued, LMC irreversibly overcame IS inhibition (the "escape" phenomenon). Addition of fresh antiserum did not alter the course of the escape. Low-temperature incub...

We report the first likely detections of erupting Dwarf Novae (DN) in an external galaxy: the Large Magellanic Cloud. Six candidates were isolated from approximately a million stars observed every second night over 11 nights with the CTIO 8K × 8K Mosaic2 CCD imager. Artificial dwarf nova and completeness tests suggest that we are seeing only the brightest of the LMC DN, probably SS Cygni-like C...
